Hepatic artery proper
Encyclopedia
The hepatic artery proper (also proper hepatic artery), arises from the common hepatic artery
and runs alongside the portal vein and the common bile duct
to form the portal triad
. The hepatic artery proper gives off a small supraduodenal artery to the duodenal bulb. Then the right gastric artery
comes off and runs to the left along the lesser curvature of the stomach to meet the left gastric artery
, which is a branch of the celiac trunk. It subsequently bifurcates into the right and left hepatic arteries. Of note, the right and left hepatic arteries may demonstrate variant anatomy. A replaced right hepatic artery may arise from the superior mesenteric artery
(SMA) and a replaced left hepatic artery may arise from the left gastric artery
. The cystic artery
generally comes off of the right hepatic artery.
Common hepatic artery
In anatomy, the common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus , duodenum and pancreas....
and runs alongside the portal vein and the common bile duct
Common bile duct
The common bile duct is a tube-like anatomic structure in the human gastrointestinal tract. It is formed by the union of the common hepatic duct and the cystic duct . It is later joined by the pancreatic duct to form the ampulla of Vater...
to form the portal triad
Portal triad
A portal triad is a distinctive arrangement in the liver. It is a component of the hepatic lobule. It consists of the following five structures:* hepatic artery* hepatic portal vein* bile duct*lymphatic vessels...

Right gastric artery
The right gastric artery arises from the common hepatic artery, above the pylorus, descends to the pyloric end of the stomach, and passes from right to left along its lesser curvature, supplying it with branches, and anastomosing with the left gastric artery.-Additional images:-External links: -...

Left gastric artery
In human anatomy, the left gastric artery arises from the celiac artery, and runs along the superior portion of the lesser curvature of the stomach. Branches also supply the lower esophagus...

Superior mesenteric artery
In human anatomy, the superior mesenteric artery arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.-Location...

Cystic artery
-Most common arrangement:In the classic arrangement, occurring with a frequency of approximately 70%, a singular cystic artery originates from the geniculate flexure of the right hepatic artery in the upper portion of the hepatobiliary triangle...
